BALlNG-PRESS- specification of Letters Patent.

Patented Jan. 2, 1906.

To aZZ whomit may concern;

Be it known that I, WINFIELD S. LIVEN- GOOD, a citizen of the UnitedStates, residing at Kansas City, in the county of Jackson and State ofMissouri, have invented certain new.

.of the power upon the head-block as the latter approaches the end ofits forward movement.

' The principal feature of the invention resides in the combination of abaling-case, a head-block reciprocably arranged therein, a cylinder, apiston-head reciprocably arranged in the cylinder, and means connectingsaid head-block to said piston-head, whereby the former is caused toadvance about triple the distance of said piston-head.

The invention further consists in the novel construction, combination,and arrangement of parts hereinafter described, and pointed out in theclaims; and in order that it may be fully understood reference will nowbe made to the accompanying' drawings, in which- Figure 1 represents avertical longitudinal sectional view taken on line I I of Fig. 3 of abaling-press embodying my improvements with the head-block at the end ofits backward movement. Fig. 2 is a Vertical longitudinal section of samewith the head-block near the end of its forward movement. Fig. 3 is aplan view of same. Fig. 4 is a vertical cross-section of thebaling-case, taken on line IV IV, showing a yoke with rollers journaledthereon employed in carrying out the invention; and Fig. 5 is amodification of same.

In said drawings, 1 designates a balingcase of any ordinaryl orpreferred construction provided with a hopper 2, through which materialis fed into the feed-chamber 3. Said baling-case is mounted upon a pairof carrying-wheels 1a in order that it may be readily transported fromplace to place.

4 designates a single-acting engine comprising a horizontal cylinder 5,`provided near its closed end with a port 5'U and at its open end withright-angled portions 6, whereby it is secured to the forward end of thebalingcase; a piston-head 7, reciprocably arranged in said cylinder; avalve-casing 8, having an inlet 8b, and a balanced valve 9, having inletand exhaust ports 9a 10, which alternately register With port 5a, andthus control the ingress and egress of the motive fiuid to and 'from thecylinder. Valve-casing 8 is provided with a centrallydisposed dependingknob 8a, adapted to be swiveled to a vehicle employed in drawing thepress from place to place.

11 designates a valve-lever secured to one end'of valve 9 by a set-screw12.

13 designates a hand-lever fulcrumed at its lower end to the lowerportion of the baling-case and extending' upwardly in the rear of hopper2 within convenient reach of the workman employed in placing hay intothe feed-chamber '3.

14 designates a 'connecting-rod pivotally secured at its ends to levers11 and 13, respectively.

15 designates a pair of piston-b ars pivotally secured at their ends topiston-head 7 and the rear member of a toggle 16, comprising two links17 18, respectively. Link 18 is pivotally secured at its forward end toheadblock 19, which latter is provided at 'its opposite sides with apair of longitudinal fianges 20, the upper edges 21 of which are turnedinwardly to form a broad surface for rollers 22, against which saidinturned portions bear during a part of the forward stroke of thehead-block, and thus prevent the latter from tipping forward whilecondensing the loose material in the feed-chamber. f

23 designates a pair of guide-rollers arranged at opposite sides of thetoggle and bearing upon the upper surfaces of the piston-bars.

24 designates a long guide-roller which bears against the under sides ofthe pistonbars and in conjunction With rollers 23 main- ,tains saidpiston-bars in a horizontal plane as they move on their forward andbackward strokes.

Rollers 22 and 23 are journaled' upon IOO to it is transverse shafts 25,eXtending through the sides of the baling-case and the sides of a yoke26, which latter comprises a U-shaped member 27, bolted at its lowerside to the bottom of the baling-case, and an arched transverse member28, secured to the upper ortion of the baling-case and the up er en s ofsaid U-shaped member` 27. Gui e-roller 24 is journaled upon a transverseshaft 24a, eX- tending through the lower portion of the yoke. One sideof link 17 also bears against roller 24, and thus causes the toggle tostraighten out to the position shown in Fig. 2 when the piston-headadvances. After said toggle attains the position above referred reventedfrom accidentally folding while a vancing by means of roller 24 and apin 29, which latter is engaged by the notched end 17a of link 17. Pin29 extends transversely through the piston-bars to which it is rivetedin order to brace said bars and prevent them from springing laterallywhile pressure is eXerted thereon when making a forward stroke.

The forward strokes of the piston-head are ordinarily limited by drawinghand-lever 13 to theposition shown by dotted line a, Fig. 2, andvthereby cutting off the flow of motive fiuid into the cylinder; but inorder to guard against said piston-head being forced out of the open endof the cylinder through failure of the workman to operate the handleverat the proper time I provide a positive stop in the form of a pin 30,extending transversely through the piston-bars, from the outer sides ofwhich latter it projects in order that said projecting ends may contactwith the rear side of yoke 26. The backward movement of hand-lever 13 islimited by valve-lever 11, contacting with a stop 11a, projectinglaterally from the ,closed end o f the cylinder, and when thevalve-lever is in contact with said lstop eXhaust-port 10 is incoincidence with port 5a, so the motive fiuid may eXhaust from thecylinder and permit the pistonhead to move backwardly. After theheadblock has reached the end of its forward stroke and the supply ofmotive fluid has been cut off from the cylinder said headblock isreturned to the end of its backward stroke by means of the expansiveforce of the material in baling-chamber 31 and the retractile spring 32,which latter is secured at its ends to a Vertical arm 33 on the closedend of the cylinder, and a screw-eye 34, secured to link 17 near thetoggle-joint 35.

In the modification Fig. 5 yoke 26CL is composed of a single casting androllers 22a are mounted upon shafts 25a, located beneath shafts 25,carrying guide-rollers 23, that bear upon flanges 20a, which latter areof less height than flanges 20 and are preferably formed integral withthe head-block instead of being riveted thereto, as are said flanges 20.

The following is a brief description of the operation of thebaling-press: After a charge of hay has been placed in feed-chamber 3the workman standing upon the baling-case draws hand-lever 13 to theposition shown by full lines, Fig. 2. This movement of the hand-leveropens the valve and permits the motive fluid to flow into the cylinderand force the piston-head forwardly. As the piston-bars advance link 17is Vushed over roller 24, and thus uickly unfol s the toggle, whichadvances t e head-block at about triple the speed to that traveled bythe iston-head until said toggle is fully exten ed, when it, thehead-block, and the piston-head all move at the same rate of speed.After the toggle has become fully extended direct pressure of the motivefiuid upon the pistonhead is transmitted to .the head-block during theremainder of the stroke. When the piston-head has completed a forwardstroke, the flow of motive fluid into the cylinder is shut off, so thatthe head-block maybe immediately returned to its starting-point throughthe recoil of the compressed hay in balingchamber 31 and the retractilespring 32, and as the piston-head moves backwardly toward the closed endof the cylinder it will be stopped before striking said closed end bythe escaping motive fiuid, which acts as a eushion between saidpiston-head and the closed end of the cylinder. As the pistonhead nearsthe closed end of the cylinder the eXhaust of the motive fiuid throughport 9 is retarded by the piston-headpartly overlapping said port, andthus temporarily reducing its area, as shown in Fig. 1.

From the above description it is obvious that I have produced abaling-press wherein a long travel of the head-block is obtained with acomparatively short stroke of 1the pistonhead, and although the initialforward movement of said head-block will be rapid and attended with butlittle power the final part of said forward movement will beaccomplisied with direct pressure ,of the motive flui Wh'i'le I haveshown and described the preferred 'construction of my baling-press, I ofcourse reserve the right to make such changes as properly fall withinthe scope of the appended claims.
